Why I Built an Ultra-Lightweight Rust & Tauri Desktop Command Center for Developers

Description and use

DevDeck is a lightweight desktop command center built with Rust and Tauri that scans workspaces, kills ghost processes, and runs scripts with live output, reducing memory usage and speeding up developer workflows.

Problem

Developers often waste time debugging ghost processes, locating project folders, and running scripts manually, leading to productivity loss.

Outcome

DevDeck reduces RAM usage to ~20-35MB, binary size under 10MB, and eliminates manual process killing and project discovery, boosting developer productivity.

Workflow

• Launch DevDeck
• Scan workspaces to index projects
• Select a project from the UI
• Run a script or target with live output
• If a port is blocked, click the kill button to terminate the ghost process

Evidence

RAM Usage: ~20MB – 35MB idle (using native OS WebViews)
